zip ties around the neck? or a tourniquet,,, would it work? i could do it in a pool, so if it doesn't directly kill me, at least i will drown

i didn't even know what a tourniquet was until a few minutes ago while doing research.
i researched and found some cases where people had caught the bus by tying a scarf around their neck.
and similar items.

it seems relatively peaceful, i mean if you pass out quickly, which i do believe you do.

maybe i'm overthinking it, because think about it like this:
if someone strangles you and keeps their hands tightly around your neck for just 2 mins, you would surely be dead, right?

so what's the difference between 2 hands and some kinda fabric around your neck?
(or zip ties)
